Description/Definition For the following questions, refer to Appendix C1 in the textbook. 1. The part of the life cycle that the cell is growing and preparing for division is called 2. In this sub-phase of interphase, there is a great deal of growth (production of inclusions and organelles) because cytokinesis was just completed. 3. The sub-phase during which the DNA is being replicated (new DNA is being synthesized) is: 4. When the chromosomes condense, the DNA wraps around proteins called: 5. Each condensed, duplicate copy of a chromosome is called: During this phase of mitosis, actin filaments draw regions of the cell membrane together near the center of the cell, creating a furrow. During this phase of mitosis, the chromosomes align at the equator of the cell. During this phase of mitosis, the chromosomes become completely condensed and visible. 6. 7. 8. 9.

During this phase of mitosis, the sister chromatids split and move to opposite poles. 13. During this process, the two daughter cells completely pinch off from each other.Explanation / Answer
1. The part of the cell cycle during which the cell is growing and preparing for the division is called interphase
This phase is divided into three parts G1 phase , S phase and G2 phase.
2. In this subphase there is a great deal of growth because cytokinesis just completed G1 phase.
3. The subphase during which the DNA is being replicated or synthesised is called S phase or Synthetic phase.
During this phase there is also replication of centrOSOME.
4. When the chromosome condense ,the DNA wraps around proteins called CHROMATIN.
5. Each condensed ,duplicate copy of chromosomse called SISTER CHROMATIDS.
6. During this phase of mitosis ,actin filaments draw regions of cell membrane together near the center of cell creating a furrow EARLY PROPHASE.
7. During this phase of mitosis ,the chromosomes align at the equator of the cell METAPHASE
8. During this phase of mitosis the chromosomes becomes completely condensed and visible is Late prophase.
9. During this phase of mitosis ,the chromosomes decondense TELOPHASE
10. During this phase of mitosis ,the nuclear envelope is broken down PROPHASE
11. During this phase of mitosis the nuclear envelope reforms TELOPHASE
12. During this phase of mitosis the sister chromatids split and move to opposite poles ANAPHASE
13. During this phrocess ,the daughter cells completely pinch off from each other CYTOKINESIS
